Variable Camshaft Timing Oil Control Solenoid

Operation



Specific to:

Toyota Camry 2007-2010

The ECM controls the Oil Control Valve (OCV), based on the signals output from the sensors. The VVT controller regulates the exhaust camshaft angle using oil pressure through the OCV. As a result, the relative position between the camshaft and the crankshaft becomes optimal, and the engine torque and fuel economy improve, and exhaust emissions decrease under overall driving conditions.

Testing



Specific to:

Toyota Camry 2007-2008

  1. Using an ohmmeter, measure the resistance between the terminals. Standard resistance: 6.9 to 7.9 ohms at 68°F (20°C). If necessary, replace the camshaft timing oil control valve assembly.
  2.  
  3. Connect the positive (+) lead from the battery to terminal 1 and the negative (-) lead to terminal 2, and check the movement of the valve.
    NOTE
    Confirm that the valve moves freely and does not stick in any position.


    NOTE
    Accumulation of foreign objects causes subtle pressure leaks. The subtle pressure leaks will cause the camshaft to advance, and this will cause a DTC to be set.

  4.  
  5. If necessary, replace the camshaft timing oil control valve assembly.
